of the speech act and larger interactive units in dialogue. The findings reveal that English diminutive suffixes are, in fact, among the most productive suffixes of the English language. While the suffixes share a number of features, each has developed its own profile, specifically regarding semantic and pragmatic features. In everyday conversation, there is a division of labour between the synthetic and the analytic type of formation concerning the communicative functions of diminutives and their distribution in discourse. The choice of formal device and its function depend crucially on pragmatic factors, notably on the illocution, the interactive status, the realisation strategy, and the politeness value of the utterances in which diminutives are employed, and also on the relationship between the interlocutors.
